Shanks & Kid Luffy

"Red-Haired" Shanks, commonly known as just "Red Hair", is the chief of the Red Hair Pirates and one of the Four Emperors that rule over the New World. Shanks is a former member of the legendary Roger Pirates, the only pirate band to successfully conquer the Grand Line, starting out his pirate career on said crew as an apprentice alongside Buggy before forming his own crew after Gol D. Roger's death. Notably, Shanks is the pirate who inspired Monkey D. Luffy to go on his own pirate journey, and his crewmate Lucky Roux found the Gomu Gomu no Mi that was accidentally eaten by Luffy. He also owned the Straw Hat that has become Luffy's signature accessory, having gifted it to the boy as part of a promise for them to meet again someday.
